# Delete Records

The DeleteOne and DeleteMany blocks in Zeromagic facilitate the removal of data from a Cosmos DB container. These blocks offer the capability to delete either a single record or multiple records from your database.

## 1. Delete One

Deletes a single record by its ID from a Cosmos DB container.

### Properties

**Container Name**: The name of the Cosmos DB container from which the record will be deleted.

**Record ID**: The unique identifier of the record to be deleted.

**Returns**: Return a `val` with the ID of deleted record.

## 2. Delete Many

Deletes multiple records based on a filter query from a Cosmos DB container.

### Properties

**Container Name**: The name of the Cosmos DB container from which the records will be deleted.

**Filter Query**: A filter query used to identify the records to be deleted. The filter query consists of a left value `(field name)` and a right value `(data to be evaluated)`.

**Returns**: Return a `val` with the IDs of deleted records.

It utilises the same condition syntax as the [If Conditions](/restapi/flow-builder/blocks/flow-control/if-else#condition-editor).

<Warning>
  Return Value : Delete records does not return any value.
